Gene silencing therapies work by stopping harmful genes from making disease-causing proteins. Instead of altering DNA, they target messenger RNA (mRNA - the “instructions” a cell reads to build proteins) so the faulty message is blocked or destroyed before it can do damage.
How it Works:
Techniques like RNA interference (RNAi) and antisense oligonucleotides (ASOs) bind to specific mRNA strands, preventing the production of proteins that drive conditions such as genetic disorders, high cholesterol and certain cancers.
Because the approach is so precise, it can reduce side effects compared to many traditional treatments. Gene silencing is already helping patients with spinal muscular atrophy and hereditary transthyretin amyloidosis, and trials are underway for neurodegenerative diseases, viral infections, and more.
The main challenge now is efficient delivery, that is, ensuring these molecules reach the right tissues, like the brain, safely and consistently. But as delivery technology advances, gene silencing therapies could transform medicine by addressing diseases at their root cause rather than simply managing symptoms.
